Resolution:
You have specified expand_doc_hol_bib in the abc60 tab_expand. This message indicates that there is an abc60 record between 584584 and 585585 which looks like this:

LKR L $$aHOL$$b000000000$$lABC01

Since there is (and can be) no abc01 record with the key of 000000000, this is a mistake.

You can just ignore it (since it's just one record), or you could run p_ret_01 in abc60 to locate the record with this particular LKR field. If the record is not deleted, you could try to find the bib record it is *supposed* to be connected to.
